Photocatalyst activation by intrinsic stimulation in TiO2–BaTiO3

Enhanced photocatalytic activity of BaTiO3@g-C3N4 for the degradation of methyl orange under simulated sunlight irradiation

“…A number of strategies have been employed to overcome the above limitations [9][10][11][12][13][14]. Recently, the construction of heterostructured composites from BaTiO 3 and other narrow-bandgap semiconductors has attracted special attention as an efficient way to extend the light response region of BaTiO 3 and improve its photocatalytic activity [9,12].…”

Coupling of piezoelectric effect with electrochemical processes

“…Semiconducting ferroelectric particles employed for the photolysis of H 2 O offers an eloquent solution to both of these challenges [89][90][91][92][93][94]. In small particles, electrons and holes are spatially confined resulting in a high rate of photoexcited charge recombination.…”

“…In these cases, the piezoelectric would be un-poled, poled, or statically strained and the resulting spontaneous or straininduced piezoelectric field would modify the energetics of electric states and the direction of migrating changes, to achieve some engineered goal [60,[89][90][91][92][93][94][95]. Recently there have been investigations into the use of dynamic applications, where a piezoelectric material is continuously and alternately strained between a tensile and compressive state resulting in a large and rapidly varying piezoelectric field within the material.…”

Dye sensitized solar cell applications of CdTiO3–TiO2 composite thin films deposited from single molecular complex

“…In a different study, optically transparent ZnTiO 3 -TiO 2 nanocomposite coatings have also shown remarkable activity in the photomineralization process of fatty-acids [23]. A nanocomposite of BaTiO 3 -TiO 2 exhibits an increased antibacterial photocatalytic activity under visible light which cannot be attained by using either pure BaTiO 3 or TiO 2 [24]. For the synthesis of multicomponent oxide systems, the aforementioned preparative routes do not always guarantee pure oxide products and in many cases, the metal to metal ratio is not strictly determined thereby undermining the performances of smart materials for various technological applications.…”
